[It might be shocking but he didn't ever interact with Ronan. It was partially because he didn't like the idea of someone getting into his dreams, even if it was to pull something into reality.]

I didn't. I did vet a reliable source [he's not going to say Yennefer's name; he doesn't know where Kyle stands with her and he knows that woman values reputation] about whether or not there were any remaining Summoned that were absolute flight risks [other than himself] and they weren't concerned about that aspect at least. That doesn't mean there isn't anyone still around, but I feel more comfortable with the odds.
